Serious question about this. The starting hand chart appears to indicate that K4os is a surprisingly superior hand to other similar high low combinations. It's there a reason or is the chart wrong?
The chart is one from a game theoretically optimal solver for the whole game, one which assumes the opponent knows your exact strategy.
K4o is raised often by this solver because the hands that you'd otherwise raise with are lacking 4s. The computer doesn't want her to raise, then see a 4 (or two) on the flop, and have her opponent know for certain that she doesn't have a 4 in her hand.
To be honest this is not something humans worry about too much pre-flop. More likely a human would raise one of K4o/K5o/K6o/K7o 100% of the time and fold the rest. Your opponent doesn't know which so you're not exploitable like above, and you don't have to worry about the nuance of "Is this hand one of the 60% I should raise this?" on a critical hand, and you get to play better hands overall.
